Yueqing Huilong’s small relay is engineered for space - constrained applications where compact size and high performance are critical. Measuring just 19mm x 15mm x 12mm, this relay features a surface - mount design (SMT) compatible with automated PCB assembly. The relay’s coil requires only 0.3W power, making it suitable for battery - powered devices. Its gold - plated contacts (1A/30V DC) offer low contact resistance (≤100mΩ), ensuring reliable signal transmission in low - voltage circuits. The small relay is constructed with a thermoplastic housing (UL94 V - 1) that resists flame and chemicals, while the hermetically sealed design prevents dust and moisture ingress. Commonly used in medical devices, portable electronics, and IoT sensors, this relay provides a mechanical life of 10 million cycles and electrical life of 1 million cycles, balancing durability with miniaturization.
